DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door lock device for a vehicle capable of performing a keyless lock operation for locking a door without using a key when the door is closed from the outside of a vehicle. If the outside handle or the inside handle is not released at this time, the door lock device cannot be locked unless the outside handle is released until the door is completely closed. The present invention relates to an automobile door lock device having a self-cancelling mechanism for unlocking a lock device.

However, in the above-described conventional vehicle door lock device, a keyless lock operation is prepared by performing a locking operation with a locking knob while once releasing the outside handle or the inside handle. Once completed, the key remains in the vehicle even if the door is closed against the operator's will, for example, due to natural phenomena such as closing the door itself due to gravity or closing due to gusts when stopping on a slope. There is a possibility that the door may be closed in the locked state while the key is locked, and there is a problem that the key may be locked.

On the other hand, a self-cancelling mechanism is known as another method for performing a keyless lock operation. The self-cancelling mechanism is disclosed in Japanese Patent Laid-Open No. 11-172977.
In order to perform the keyless locking operation, the sill knob of the opened door is first locked. Then, if the door is closed while releasing the outside handle or the inside handle of the door, the door is closed in a locked state, and the keyless lock is completed. At this time, if the door is closed without releasing the outside handle or the inside handle, the locked state is canceled and the door is unlocked. This is the function of the self-cancelling mechanism, the latch rotates to engage the striker when the door is closed, and the movement is transmitted to the lock lever to which the sill knob is connected via the ratchet lever, open lever, and connection link, and the lock lever Is to be unlocked.

In order to solve the above-mentioned problem in the conventional door lock device, a method of using a known self-cancelling mechanism is conceivable. However, the structure becomes complicated, the number of parts increases, and the price increases. A new problem may occur.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, an object of the present invention is to provide a lockless operation by releasing the outside handle or the inside handle and performing a keyless lock operation even if the door closing operation is completed. If the door is not closed while the outside handle is being released, the locked state is canceled when the door is closed and unlocked, preventing the key from being locked. It is to provide in.

As shown in FIG. 9, the contact portion 9d of the sub-lever 9 is located above the contact portion 9b of the open lever 5 so that the contact portion 9b of the open lever 5 can move. It can be transmitted to the contact portion 9d. First, in the process of reaching the half-latch position where the latch 2 barely engages the striker 1, the open swinging counterclockwise in conjunction with the pole 3 swinging counterclockwise as shown by the imaginary line in FIG. The locking portion 9e of the sub-lever 9 which has been engaged with the blocking portion 5b of the lever 5 is released, and the sub-lever 9 moves upward by the urging force of the spring 6c, and the blocking portion 5b of the open lever 5 and the sub-lever 9
Is in a position where the contact portion 9d is opposed to the contact portion 9d.

At this point, as the door is further closed and the latch 2 reaches the full latch position where the latch 2 is completely engaged with the striker 1, as shown by the solid line in FIG. After being pushed by 2f and largely swinging clockwise, it swings counterclockwise again at the full latch position and stops. In conjunction therewith, the blocking portion 5b of the open lever 5 swinging clockwise pushes the contact portion 9d of the sub-lever 9 in the release direction, and the connected second unlocking lever 8
Is rocked in the unlocking direction. Along with this, the knob lever 16 connected to the second locking / unlocking lever 8 also swings, and moves the connected locking knob 13 upward, which protrudes from the upper part of the inner side surface of the door in the unlocking direction. In this state, when the outside handle outside the vehicle or the inside handle inside the vehicle is released, the release lever 6 is rotated clockwise, as shown in FIG. When the sub-lever 9 is lowered, the action portion 9c abuts on the engagement portion 5a of the open lever 5, and the open lever 5 is rotated clockwise to open the door. be able to.

As described above, when the door is opened and the locking operation is performed while the outside handle is released, the sub-lever 9 is held by the open lever 5 in the locked state, and the preparation for the keyless locking operation is completed. Here, even if the release operation of the outside handle is interrupted, the locked state of the sub lever 9 is maintained, so that the usability is good. Next, when the door closing operation is performed with the outside handle release operation performed, the door can be closed in the locked state, and the keyless lock operation is completed. At this time, if the door closing operation is performed without performing the release operation of the outside handle, the self-cancellation is performed and the door is closed in the unlocked state. That is, even after the preparation for the keyless lock operation is completed, when the door is closed due to a natural phenomenon or the like contrary to the operator's will,
Since the locking is canceled, the key is reliably prevented from being locked in the vehicle.

Further, since the member for preventing the locking operation when the door is opened and the member for pressing the sub-lever 9 to the unlock position at the time of self-cancellation are also used by the blocking portion 5b of the open lever 5, the number of parts is small. The structure can be simple.

[0032]

According to the first aspect of the present invention, the blocking portion that pushes the sub-lever back in the release direction when the open lever self-cancels is positioned so that the locking of the sub-lever can be prevented by the projection of the latch when the opening lever is opened. With simple changes, when the door lock device is open when the door is opened, the outside handle or inside handle cannot be locked unless it is released, in addition to the self-cancel function, the number of parts is small and the structure is simple It is possible to provide a simplified door lock device.

According to the second aspect of the present invention, when the door is opened, the outside handle or the inside handle is released and the locking operation is performed, and then the hand is released from the operated handle until the door is closed. However, since the sub-lever is engaged with the open lever to maintain the release state, it is easy to use.
